Interpretive Summary: Since 1991, producers in Ukraine have freedom to plan their crop production systems. The changes in cropping systems implemented by Ukrainian producers have affected weed dynamics. This paper informs weed scientists in the U.S. of trends with weed dynamics in Ukraine and describes management tactics used by producers, with the goal of encouraging interaction between scientists of both countries. Perennial weeds especially have escalated rapidly throughout Ukraine; the most prevalent species is field bindweed. The causes of this change in weed dynamics include less diverse crop rotations, an infrastructure and economic situation that disrupts planned management tactics, herbicide resistance, and a lack of comprehensive weed management plans for most crops. Ukraine is seeking to develop ecologically-based weed management and sustainable cropping systems based on diverse rotations and no-till.

Technical Abstract: In 1991, Ukraine became a self-governing country. With the change in government, producers gained freedom to plan their crop production systems. The changes in cropping systems implemented by Ukrainian producers have affected weed dynamics. The purpose of this paper is to inform weed scientists in the U.S. of trends with weed dynamics in Ukraine, describe management tactics used by producers, and encourage interaction between scientists of both countries. Weed densities, especially perennial weeds, have escalated rapidly throughout Ukraine. Two weeds in particular, field bindweed and common ragweed, are now prominent in most crops. The causes of this change in weed dynamics include less diverse crop rotations, an infrastructure and economic situation that disrupts planned management tactics, herbicide resistance, and a lack of comprehensive weed management plans for most crops. Ukraine is seeking to develop ecologically-based weed management systems as well as sustainable cropping systems based on diverse rotations and no-till.
